I'm so glad I made games as a hobby before I got anywhere close to graduating. Killed that dream real fast. It felt like shit having to play your own game so many times the game lost all meaning and it was hard to gauge if it was even fun anymore.
I tried to teach myself piano. I actually enjoyed it when I was learning it, however I was really enjoying the progress I was making and less about the music I was playing. I wonder though if you get really good with music, you can probably learn and play new pieces much more quickly so maybe the magic won't fade as quickly.
I think it's even stronger, because sometimes you'll repeat the same 10 seconds a thousand time to master it until you feel like jumping out of the window.
